DRAFT-RIGGIN GL SPECIFICATION formingpart of Letters Patent No. 693,250, dated February 11, 1902. Application filed April 6, 1901. Serial No. 54,574. (No model.)

To aZZ whom it may concern.-

Be it known that we, CHARLES A. FERNALD and GEORGE GALLEY, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Draft-Rigging, of which the following is a specification.

Our invention relates to the improvement of draft-rigging for railway-cars; and the objects of our invention are to provide a simple and reliable construction of this character which will relieve the draft-timbers from undesirable strain and otherwise protect said timbers against breakage, 'to so construct our improved draft-rigging as to distribute'the strain of the draw-bar, and to produce other improvements in details of construction and arrangement of parts,which will be more f ully pointed out hereinafter. These objects we accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is an under side view of our improved draft-rigging. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view in perspective of one of the metallic holding blocks or brackets which we employ in the manner hereinafter described, Fig. 4 is a central vertical section of the rearward extension of the draw-bar, illustrating its spring connection with the transverse holding-bar. Fig. 5 is a horizontal section through the forward portions of the longitudinal draft-timbers and the rear portion of the draw-bar body, and Fig. 6 is an enlargedtransverse section through the car sill on line y y of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

Of the draft-frame, 1 represents the parallel longitudinal draft-timbers,each of which may consist of the united upper and lower sections 1 and2 or be formed integral, ifdesired.

2 represents the front transverse draftframe sill, which connects the ends of the upper timbers 1, and 3 is the transverse car cross-sill or transom, against which the rear ends of the upper sections of the timbers 1 abut.

4 represents a draw-bar of any desirable character, the stem or shank portion 4 of which extends rearwardly between the timbers 1 and beneath atransverse timber-connecting plate 5. In constructing the shank or inner end portion of the draw-bar the same is provided with a rigid rearwardly-extending metallic yoke or oblong frame 4". Through a'slotted opening 4 of the shank portion 4 passes, as indicated more clearly in Fig. 4 of the drawings, a transverse bar 6, the latter having its end portions extending loosely through oppositely-located openings 1 in the forward end portions of the timber sections or portions 2. With the outwardly-projecting end portions of the transverse bar 6 are connected the forward ends of rearwardly-extending strain-rods 7,'these rods extending on the outer sides of the longitudinal drafttimbers 1, passing loosely through openings in the sill or transom 3, and terminating at points a short distance from the rear side of the latter. Upon the rear end portions of these strain-rods 7 are mounted bearing collars or stops 8, and between the latter and suitable frame-plates 9, which abut against the rear side of the sill 3, are arranged springs '10, the springs 10 preferably inclosin'ginternal springs 11.

Opposite the yoke or oblong frame termi nation 4 the inner sides or surfaces of the timbers 1 are suitably recessed to receive the central vertically-channeled portion 12 and end spurs 13 of metallic blocks or brackets 14. The oppositely located central vertical recesses 15 of these blocks 14 are adapted to receive the ends of a transverse holding-bar 16, which/extending through the frame or yoke extension 14 of thedraw-bar has its central portion provided with oppositely-projecting bosses 16*, over which fit the ends of springs 17 and 18, the spring 17 bearing between said bar 16 and the rear end of the yoke 4", and the spring 18 bearingbetween said bar 16 and thebody of the draw-bar 4. These springs 17 and 18 are also surrounded by external springs 19 and 20. Upon the lower sides of the timbers 1 we providelongitudinalmetallic cover-plates 21, these plates thus'cove'ring therecesses of the timbers 1, into which are fit the projections 12 and 13 of the castings 14. As shown more clearly in Fig. 2 of the drawings, the forward ends of the plates 21 are provided on their sides with downwardly-pro- Ice jecting cars 21, which embrace opposite sides of the timbers 1 and through the slotted openings of which passes loosely the bar 6.

From the construction which we have herein shown and described it will be seen that the forward and backward strain of the drawbar is distributed between the blocks 14: and the car transom or sill 3 and that the direct strain is thus removed from the drafttimbers. It will also be seen that the springs which are arranged in front and rear of the draft-bar 16 and the springs 10 and 11 upon the rods 7 will serve to cushion the draw-bar, and thus relieve the timbers or draft-framework from shock. In this connection it may be observed that it has been common to extend the draft-timbers throughout the length of the car and likewise side draft-rods; but from the construction which we have shown and described it will be seen that the side rods are terminated a short distance in rear of the sill 0r transom 3, and the latter is made to receive a desirable proportion of the strain resulting from a pull on the draw-bar. It

will also be seen that the manner of connecting the draft-bar 16 with the draw-bar, consisting in providing said draft-bar with projections which receive springs on opposite sides of the bar, is such as to admit of such lateral swinging movement of the draw-bar as may be required.

Having now fully described our invention, what we claim, and desire to secure by Letters Patent, is

In a draft-rigging, the combination with parallel longitudinal draft-timbers 1, a drawbar having its shank portion extending between said timbers and provided with a framelike extension 1 of brackets 14 secured to the inner sides of the timbers 1, a bar 16 extending through the draw-bar extension and en gaging recesses in said brackets, springs arranged on opposite sides of said bar 16 Within said extension, a transverse bar 6 passing through slotted openings in saidtimbers 1 and in the draw-barshank, draft-rods 7, engaging the ends of said bar 6 and passing through the transom or sill 3 and springs arranged between the ends of said rods 7 and the rear side of said transom, substantially as specified.
